Application doesn't even start on Linux Mint 19.2

[Karl Zeilhofer]

Hi,

I tried to run FlatCAM from the sources on a Linux Mint 19.2.

First, the file setup_ubuntu.sh is stored with Windows line endings, which prevents the shell to execute the script. I fixed that and then ran it.

Afterwards I gave FlatCAM.py executable flag and started it.
The mouse cursor changed to a cross, but nothing else happens. No application window appears. When I click then somewhere, I get this error in the command line:

 @ error/constitute.c/WriteImage/1037.

after a second click, following errors appear:

' @ error/constitute.c/WriteImage/1037.
./FlatCAM.py: line 3: $'\r': command not found
from: can't read /var/mail/PyQt5
from: can't read /var/mail/PyQt5.QtCore
from: can't read /var/mail/FlatCAMApp
from: can't read /var/mail/flatcamGUI
./FlatCAM.py: line 8: $'\r': command not found
from: can't read /var/mail/multiprocessing
./FlatCAM.py: line 12: $'\r': command not found
./FlatCAM.py: line 18: syntax error near unexpected token `('
'/FlatCAM.py: line 18: `def debug_trace():

and the process stoppes here, returning to the shell’s prompt.

Did I miss anything in the ‘installation process’?

Greets, Karl

PS: I used the zip-file for getting the sources.

I now checked it out with git clone … and checked out the branch Beta.

The behaviour is now the same, but the messages are a bit different:

import-im6.q16: not authorized `sys' @ error/constitute.c/WriteImage/1037.
import-im6.q16: not authorized `os' @ error/constitute.c/WriteImage/1037.

./FlatCAM.py: line 18: `def debug_trace():'

Hi Karl,

The development is done in Windows so you have the reason for the line endings. I’m not a Linux expert but you may need to run everything as root (su). I mean install, and running the software. It looks like the PyQt5 (al least) did not install correctly. You may have a “read or write rights” problem.

Best regards,
Marius

Also please make sure first that the python and pip is installed on your OS.
Make sure that the command:

pip3

launched from the terminal return a meaningful result.

Issue is not related to the FlatCAM application but to how the OS is setup/configured.
